In this paper, we propose a new approach to monitor a solar plant in real-time using an embedded vision system, comprised mainly of raspberry Pi3 card, GPS and thermometer sensors, and an HD camera module. This approach consists on using image processing techniques on solar energy fields. It is implemented on two steps, the first apply the digital watermarking technique based on discrete cosine transform...
Solar panels outer surface inspection is among the most challenging tasks which burden the solar plants supervisors. An automatic inspection based on image processing ensured by robots seems beneficial. In our approach, a robot equipped with an HD camera and a processing unit browses a set of solar panels (placed alongside). Afterward, the robot captures a series of successive images containing a...
One of the most critical issues facing solar plants is to ensure an efficient monitoring of installations, such as localizing dust or broken panels. Filming with robots or drones is widely used, but it is difficult to exploit directly the captured videos. In order to facilitate the monitoring task, we propose a technique to prepare a large panoramic image view of the desired area from the captured...
The International Renewable and Sustainable Energy Conference (IRSEC'16) was really a very special edition owing to the wonderful opportunity it has to be held among the official events organized within the “Conference of the Parties” (COP22) of the United Nations Framework Convention on Climate Change (UNFCCC).
In this paper, we introduce a novel edge directed image detail preserving impulse noise removal algorithm. Our approach is based on local image directionality features. Local edge features are analysed on both a downsampled version of the image and the noisy image, and both soft an sharp edges are considered for selective noise removal. Experimental results on a set of standard images show our technique...
Cloud coverage obscures the sunlight, it can be identified as the major factor that significantly decreases the total irradiance received by photovoltaic panels, and then the power generation is intermittent. In this paper, and in order to predict the energy production by a solar installation, we analyze the acquired ground based images of the sky to extract its actual status (clear, partially cloudy,...
The 4th edition of the International Conference on Multimedia Computing and Systems (ICMCS'16) consolidates its position among IEEE renowned conferences covering topics and issues related with multimedia technologies. These technologies are reshaping modern societies at different levels and through applications as diverse as medicine, education, virtual reality, augmented reality and entertainment.
QR codes have become useful and efficient data storage tools which are exploited in many commercial applications including product tracking, website redirection, etc. A QR code is a 2-dimensional barcode localised through three finder patterns (three squares characterised by a series of alternative black and white modules at ratios 1∶1∶3∶1∶1) placed in its three corners. QR codes are generally placed...
The crux for renewable energy is the cost of setting up the solar farm, and the efficiency of monitoring the power output. Usually, solar farms occupy a large land area, which arises a tremendous need for remote monitoring of solar panels state. Panel images can be used to evaluate panels' state: surface dust, cells state, broken panels, etc. In this paper, we propose a process to ensure a remote...
The development of a solar plant is an investment that requires the allocation of a large land area, where a huge number of panels are installed. Each panel has manufacturer features written usually in the back. This data with corresponding panel photo are interesting to save in order to ensure an efficient monitoring. The task of identifying panels with related features seems arduous and requires...
Tracking and predicting cloud motion was a key factor in getting the most out of solar PV installations. This paper presents a method of tracking cloud motion using ground-based omnidirectional images acquired by a catadioptric camera. This sensor offers wide field of vision that allows us a longtime of clouds tracking. Acquired images are processed to extract the relative position of the sun and...
Sustainable energy is the sustainable provision of sustainable energy development that meets the needs of the present without compromising the ability of future generations to meet their needs. Technologies that promote sustainable energy are mainly based on renewable energy sources, such as hydroelectricity, solar energy, wind energy, wave power, geothermal energy, bio-energy, tidal power and also...
Localization need is appeared with the evolution of mobile communication devices. Nowadays, smart phones are equipped with many sensors that allow position estimation. Based on localisation, many applications and values added services are developed to meet the increasing users need. In order to design localization system, it requires first to understand the fundamental localization principles and...
The very important success of the two former editions of the International Conference on Multimedia Computing and systems, namely, ICMCS'09 and ICMCS'12, which took place respectively in Ouarzazate (or Warzazat), Morocco in April 2–4, 2009 and Tangiers, Morocco in May 10–12, 2012, was a very good incentive for us to launch a third edition of this conference in an effort to make it a regular appointment...
The Mediterranean Space of Technology and Innovation with the partnership of the Moroccan Agency of Solar Energy (MASEN), National Higher School of Information Technology (ENSIAS), Rabat, Morocco and the Poly-disciplinary Faculty of Ouarzazate, Morocco organized the First Edition of the International Renewable and Sustainable Energy Conference (IRSEC'13) in Ouarzazate, Morocco in March 7–9, 2013.
In this paper, we propose a novel method to embed Electronic Patient Records (EPR) data in medical images. Indeed, after liberating a zone by compressing the image Least Significant Bit plan using the Huffman coding, the EPR is encrypted by an Elliptic Curve Cryptosystem (ECC) and inserted into this zone. The proposed method improves medical security performance and reduces the computation cost related...
